I would like to convert half my garage into a study room for the next few years (about 4 years or so). When I sell the property I may take it down and return the garage to its original use; so no planning or formal changes required.
So my question is; as the garage is single brick what sort of stud wall should I construct 4” x 2” chipboard/MDF/plasterboard and what should I put on the top of this study room as it has an asbestoses corrugated roof.
Also could I use 50mm polystyrene as the insulation between the 4” x 2”’s and what on the floor?
Do I need to waterproof the brickwork (inside or outside)?
A local builder quoted around £700/£800 and mentioned gymsol material – never heard of it.
At that price I need to do it myself.
Many thanks,
Graham.
